Optical encryption terminal, cryptography key distribution system and method of generating cryptography keys in a cryptography key distribution system Patent
2018, (In an aspect, the present invention provides an optical encryption terminal (110A) for generating and distributing a cryptographic key signal in a cryptography key distribution system (100) having at least two optical encryption terminals (110A, 110B). The optical encryption terminal (110A) comprises an electronic processing unit (116A) and the optical encryption terminal (110A) is configured to selectively receive optical input signals (OIS-A) generated by a source (120A) of electromagnetic radiation and optical input signals (OOS-B) generated by a further optical encryption terminal (110B), and to selectively output first optical output signals (OOS-AB) to a detection element (130A) and second optical output signals (OOS-A) to the further optical encryption terminal (110B), wherein the first optical output signals (OOS-AB) are based on the optical input signals (OOS-B) generated by the further optical encryption terminal (110B) and transformed in accordance with an optical encryption pattern (114A) provided at the optical encryption terminal (110A). Furthermore, the optical encryption terminal (110A) is configured to determine, using the electronic processing unit (116A), a cryptographic key signal (keyA) on the basis of at least one radiometric and/or photometric quantity associated with the optical output signals (OOS-AB) detected by the detection element (130A).).
Analytic device including nanostructures Patent
2017, (A device for detecting an analyte in a sample comprising: an array including a plurality of pixels, each pixel including a nanochain comprising: a first nanostructure, a second nanostructure, and a third nanostructure, wherein size of the first nanostructure is larger than that of the second nanostructure, and size of the second nanostructure is larger than that of the third nanostructure, and wherein the first nanostructure, the second nanostructure, and the third nanostructure are positioned on a substrate such that when the nanochain is excited by an energy, an optical field between the second nanostructure and the third nanostructure is stronger than an optical field between the first nanostructure and the second nanostructure, wherein the array is configured to receive a sample; and a detector arranged to collect spectral data from a plurality of pixels of the array).
